Thanks for infos Roy, I didn't know that remediosae is considered as a form of boxallii and not a variety.
Philippe, thats in the Kew list under the guidance of a few boffins. I have this and the 'type' variety of lamellata
and looking for boxallii, these variety names are used by everyone including their country of origin. There is no way I'm changing the label regardless of what the Kew clowns say.
